SPINDLE-SUPPORT FOR SPINNING=MACHINES.

' SPECIFICATION forming part of Letters Patent No. 362,944, dated May 17, 1887.

Application filed July 2, 1856. Serial No. 206,947.

i To aZZ whom it may concern.-

Be it known that 1', WILLIAM F. DRAPER, of Hopedale, county of Vorcester, and State of Massachusetts, have invented an Improvement in Spindle-Supports forSpinningMachines, of which the following description, in connection with the accom rvanying drawings, is a specification, like letters on the drawings represent ing like parts.

Prior to my invention it has been customary to place the pintlcs of sleeve-whirl spindles in bolsters inserted loosely within bolster-cases rigidly attached to the bolster-rail, both the said bolstercase and bolster entering the space between the sleevewhirl and the pintle of the spindle, the bolster being surrounded by elastic packing or oil. So, also, prior to my invention a spindle has been run in a rigid support held upon the rail by a spring, as in United States Patent No. 253,572, and so, also, supports have been loosely held above or with relation to the rail by a single pin, which also acts as a stop to limit the amount of looseness between the rail and support.

My invention has for its object to yet further simplify the construction of spindle-supports of the class employed to form bearings for what are known as top spindles.

My invention consists in the construction and combination of parts, hereinafter particu larly set forth and claimed.

Figure 1 shows a spindle-support embodying my invention, the spindle and limitingscrews being in elevation, the sleeve-whirl, bolster, and rail being in section. Fig. 2 isa plan or top View of Fig. 1, the spindle being omitted; and Fig. 3 shows one of the limiting screws.

The rail to and spindle I), having a sleevewhirl, areand may be of usual construction.

My improved spindle-support consists, essentially, of a rigid or stiff tube, 0, having a llange or foot, (I, which is shown as resting on or above the rail a, the projection c at the lower end of the support entering loosely the usual hole in the rail.

Thelimiting screws'orstuds f f, (herein shown as two in number, and so named because they (No model.)

serve to limit the extent of movement of the bolster upon or with relation to the rail (0,) are located at opposite sides of the tube 0, and are shown as provided with shoulders, as at 2, which, when the threaded parts of the said screws are screwed fully into the threaded holes in the rail, come to a stop against some fixed part, as a part of the rail, leaving the underside of the head of the screw su'liiciently above the top of the rail and the flange as to permit the flange of the bolster to move upon or with relation to the rail as the spindle moves to accommodate itself to its unbalanced load.

The space between the projection c and the part of the rail surrounding it is sufficient to allow the bolster to move laterally for the 1100- essary distance to meet the requirements of the spindle.

The diameter of the opening in the flange or foot of the bolster is greater than the diameter of the shoulder of the screws or studs within said opening.

I claim The sleeve-whirl spindle, the rail or base a, and the bolster having a rigid tube-like portion, 0, extended into the sleeve-whirl,and eonstitut-ing the only lateral bearing for the spindle, and having a flange or foot, (Z, extended therefrom, combined with the limiting screws or studsf, provided with shoulders 2, and having these shouldered portions of greaterdiameter than the threaded portions and fitting in screw-holes in the flange of greater diameter than the shouldered portions, so that when the threaded portions are fully inserted into the rail or base the shoulders come to rest upon the rail or base, and sufficient space between the flange and screws is left for the free movement of the bolster and its flange or foot under the heads of the screws or studs, substan tially as described.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.
